              AGREEMENT AND PLAN OF MERGER, dated as of March 14, 2000 (the
"Agreement"), among ALCOA INC., a Pennsylvania corporation ("Alcoa"), OMEGA
ACQUISITION CORP., a Delaware corporation (the "Purchaser"), and CORDANT
TECHNOLOGIES INC., a Delaware corporation (the "Company").

          WHEREAS, the Boards of Directors of Alcoa, the Purchaser and the
Company deem it advisable and in the best interests of their respective
stockholders that Alcoa acquire the Company upon the terms and subject to the
conditions provided for in this Agreement;

          WHEREAS, in furtherance thereof it is proposed that the acquisition be
accomplished by the Purchaser commencing a cash tender offer (as it may be
amended from time to time as permitted by this Agreement, the "Offer") to
purchase all of the issued and outstanding shares of common stock, par value
$1.00 per share, of the Company  (the "Company Common Stock") and the associated
Rights (the shares of Company Common Stock and any associated Rights are
referred to herein as "Shares"), for $57.00 per Share (such amount or any
greater amount per Share paid pursuant to the Offer being hereinafter referred
to as the "Offer Price"), subject to applicable withholding Taxes, net to the
seller in cash, upon  the terms and subject to the conditions set forth in this
Agreement;

          WHEREAS, the Board of Directors of the Company has approved the Offer
and the Merger and resolved to recommend that holders of Shares tender their
Shares pursuant to the Offer and approve and adopt this Agreement and the
Merger; and

          WHEREAS, the Boards of Directors of Alcoa (on its own behalf and as
the sole stockholder of the Purchaser), the Purchaser and the Company have each
approved this Agreement and the merger of the Purchaser with and into the
Company (the "Merger") in accordance with the General Corporation Law of the
State of Delaware (the "DGCL"), in the case of each of the Company and the
Purchaser, and in accordance with the Pennsylvania Business Corporation Law, in
the case of Alcoa, and upon the terms and conditions set forth in this
Agreement.

          NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, and intending to be
legally bound hereby, Alcoa, the Purchaser and the Company agree as follows:

 
                                   ARTICLE I


          Section 1.1  The Offer.
                       --------- 

          (a) Provided that this Agreement shall not have been terminated in
accordance with Section 7.1 and none of the events set forth in paragraphs (a)
through (i) of Annex A hereto shall have occurred or be existing (and shall not
have been waived by the Purchaser), the Purchaser shall commence (within the
meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) the Offer as promptly as reasonably practicable after the date
hereof, but in no event later than five business days after the public
announcement of the execution of this Agreement.  The obligation of the
Purchaser to accept for payment and pay for Shares tendered pursuant to the
Offer shall be subject only to the satisfaction of the condition that there be
validly tendered and not withdrawn prior to the expiration of the Offer that
number of Shares which represents at least a majority of the then outstanding
Shares on a fully diluted basis (the "Minimum Condition") and to the
satisfaction or waiver by the Purchaser of the other conditions set forth in
Annex A hereto.  The Company agrees that no Shares held by the Company or any of
its Subsidiaries will be tendered to the Purchaser pursuant to the Offer.  The
Purchaser expressly reserves the right to waive any of such conditions (other
than the Minimum Condition), to increase the price per Share payable in the
Offer and to make any other changes in the terms of the Offer; provided,
however, that no change may be made without the prior written consent of the
Company which decreases the price per Share payable in the Offer, reduces the
maximum number of Shares to be purchased in the Offer, changes the form of
consideration to be paid in the Offer, modifies or amends any of the conditions
set forth in Annex A hereto, imposes conditions to the Offer in addition to the
conditions set forth in Annex A hereto, waives the Minimum Condition or makes
other changes in the terms and conditions of the Offer that are in any manner
adverse to the holders of Shares or, except as provided below, extends the
Offer.  Subject to the terms of the Offer and this Agreement and the
satisfaction or earlier waiver of all the conditions of the Offer set forth in
Annex A hereto as of any expiration date of the Offer, the Purchaser will accept
for payment and pay for all Shares validly tendered and not withdrawn pursuant
to the Offer as soon as it is permitted to do so under applicable law.
Notwithstanding the foregoing, the Purchaser may, without the consent of the
Company, (i) extend the Offer beyond the scheduled expiration date, which shall
be 25 business days following the date of commencement of the Offer, if, at the
scheduled expiration of the Offer, any of the conditions to the Purchaser's
obligation to accept for payment and to pay for the Shares shall not be
satisfied or, to the extent permitted by this Agreement, waived or (ii) extend

                                       2

 
the Offer for any period required by any rule, regulation or interpretation of
the Securities and Exchange Commission (the "SEC") or the staff thereof
applicable to the Offer, other than Rule 14e-5 promulgated under the Exchange
Act.  Unless the Company advises the Purchaser that it does not wish the
Purchaser to extend the Offer, the Purchaser shall extend the Offer from time to
time until the earlier of (A) the date that is 30 days after the date on which
the Regulatory Condition (as defined in Annex A) is satisfied or (B) the Drop
Dead Date, in the event that, at the then-scheduled expiration date, all of the
conditions of the Offer set forth in Annex A hereto have not been satisfied or
waived as permitted by this Agreement.  Any extension of the Offer pursuant to
the preceding sentence of clause (i) of the second preceding sentence or this
Section 1.1 shall not exceed the lesser of ten business days or such fewer
number of days that the Purchaser reasonably believes are necessary to cause the
conditions of the Offer set forth in Annex A hereto to be satisfied.  The
Purchaser shall provide a "subsequent offering period" (as contemplated by Rule
14d-11 under the Exchange Act) of not less than three business days following
its acceptance for payment of Shares in the Offer.  On or prior to the dates
that the Purchaser becomes obligated to accept for payment and pay for Shares
pursuant to the Offer, Alcoa shall provide or cause to be provided to the
Purchaser the funds necessary to pay for all Shares that the Purchaser becomes
so obligated to accept for payment and pay for pursuant to the Offer.  The Offer
Price shall, subject to any required withholding of Taxes, be net to the seller
in cash, upon the terms and subject to the conditions of the Offer.

          (b) As promptly as practicable on the date of commencement of the
Offer, the Purchaser shall file with the SEC a Tender Offer Statement on
Schedule TO (together with all amendments and supplements thereto, the "Schedule
TO") with respect to the Offer.  The Schedule TO shall contain or incorporate by
reference an offer to purchase (the "Offer to Purchase") and forms of the
related letter of transmittal and all other ancillary Offer documents
(collectively, together with all amendments and supplements thereto, the "Offer
Documents").  Alcoa and the Purchaser shall cause the Offer Documents to be
disseminated to the holders of the Shares as and to the extent required by
applicable federal securities laws. Alcoa and the Purchaser, on the one hand,
and the Company, on the other hand, will promptly correct any information
provided by it for use in the Offer Documents if and to the extent that it shall
have become false or misleading in any material respect, and the Purchaser will
cause the Offer Documents as so corrected to be filed with the SEC and to be
disseminated to holders of the Shares, in each case as and to the extent
required by applicable federal securities laws.  The Company and its counsel
shall be given a reasonable opportunity to review and comment upon the Schedule
TO before it is filed with the SEC.  In addition, Alcoa and the Purchaser agree
to provide the Company and its counsel with any comments, 

                                       3

 
whether written or oral, that Alcoa or the Purchaser or their counsel may
receive from time to time from the SEC or its staff with respect to the Offer
Documents promptly after the receipt of such comments and to consult with the
Company and its counsel prior to responding to any such comments.

          Section 1.2  Company Actions.
                       --------------- 

          (a) The Company hereby approves of and consents to the Offer and
represents and warrants that the Company's Board of Directors, at a meeting duly
called and held, has (i) determined that the terms of the Offer and the Merger
are fair to and in the best interests of the stockholders of the Company, (ii)
approved this Agreement and approved the transactions contemplated hereby,
including the Offer and the Merger and (iii) resolved to recommend that the
stockholders of the Company accept the Offer, tender their Shares to the
Purchaser thereunder and approve and adopt this Agreement and the Merger.
Subject to Section 5.7, the Company hereby consents to the inclusion in the
Offer Documents of the recommendation of the Board described in the immediately
preceding sentence.

          (b) As promptly as practicable on the date of commencement of the
Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 (together with all amendments and supplements
thereto, the "Schedule 14D-9") which shall contain the recommendation referred
to in clause (iii) of Section 1.2(a) hereof.  The Company further agrees to take
all steps necessary to cause the Schedule 14D-9 to be disseminated to holders of
the Shares as and to the extent required by applicable federal securities laws.
The Company, on the one hand, and each of Alcoa and the Purchaser, on the other
hand, will promptly correct any information provided by it for use in the
Schedule 14D-9 if and to the extent that it shall have become false or
misleading in any material respect, and the Company will cause the Schedule 14D-
9 as so corrected to be filed with the SEC and to be disseminated to holders of
the Shares, in each case as and to the extent required by applicable federal
securities laws.  Alcoa and its counsel shall be given a reasonable opportunity
to review and comment upon the Schedule 14D-9 before it is filed with the SEC.
In addition, the Company agrees to provide Alcoa, the Purchaser and their
counsel with any comments, whether written or oral, that the Company or its
counsel may receive from time to time from the SEC or its staff with respect to
the Schedule 14D-9 promptly after the receipt of such comments and to consult
with Alcoa, the Purchaser and their counsel prior to responding to any such
comments.

                                       4

 
          (c) The Company shall promptly furnish the Purchaser with mailing
labels containing the names and addresses of all record holders of Shares and
with security position listings of Shares held in stock depositories, each as of
a recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
non-objecting beneficial owners of Shares.  The Company shall furnish the
Purchaser with such additional information, including, without limitation,
updated listings and computer files of stockholders, mailing labels and security
position listings, and such other assistance as Alcoa, the Purchaser or their
agents may reasonably require in communicating the Offer to the record and
beneficial holders of Shares.  Subject to the requirements of applicable law,
and except for such steps as are necessary to disseminate the Offer Documents
and any other documents necessary to consummate the Offer or the Merger, Alcoa
and the Purchaser shall hold in confidence the information contained in such
labels, listings and files, shall use such information solely in connection with
the Offer and the Merger, and, if this Agreement is terminated in accordance
with Section 7.1 or if the Offer is otherwise terminated, shall promptly deliver
or cause to be delivered to the Company all copies of such information, labels,
listings and files then in their possession or in the possession of their agents
or representatives.

          Section 1.3  Directors of the Company.
                       ------------------------ 

          (a) Promptly upon the purchase of and payment for Shares by the
Purchaser or any of its affiliates pursuant to the Offer, Alcoa shall be
entitled to designate such number of directors, rounded up to the next whole
number, on the Board of Directors of the Company as is equal to the product
obtained by multiplying the total number of directors on such Board (giving
effect to the directors designated by Alcoa pursuant to this sentence) by the
percentage that the number of Shares so purchased and paid for bears to the
total number of Shares then outstanding.  In furtherance thereof, the Company

          Section 2.8  Exchange of Certificates.
                       ------------------------ 

          (a) Exchange Agent.  Prior to the Effective Time, Alcoa shall
              --------------                                           
designate a bank or trust company reasonably acceptable to the Company to act as
agent for the holders of the Shares (other than Shares held by Alcoa and its
Subsidiaries, the Company and its Subsidiaries, and Dissenting Shares) in
connection with the Merger (the "Exchange Agent") to receive in trust, the
aggregate Merger Consideration to which holders of Shares shall become entitled
pursuant to Section 2.7(b).  Alcoa shall deposit such aggregate Merger
Consideration with the Exchange Agent promptly following the Effective Time.
Such aggregate Merger Consideration shall be invested by the Exchange Agent as
directed by Alcoa or the Surviving Corporation.

          (b) Exchange Procedures.  Promptly after the Effective Time, Alcoa and
              -------------------                                               
the Surviving Corporation shall cause to be mailed to each holder of record, as
of the Effective Time, of a certificate or certificates, which immediately prior
to the Effective Time represented outstanding Shares (the "Certificates"), whose
Shares were converted pursuant to Section 2.7(b) into the right to receive the
Merger Consideration, a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon proper delivery of the Certificates to the Exchange Agent and shall be
in such form and have such other provisions as Alcoa may reasonably specify) and
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration.  Upon surrender of a Certificate for cancellation
to the Exchange Agent or to such other agent or agents as may be appointed by
Alcoa, together with such letter of transmittal, properly completed and duly
executed in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration for each Share formerly represented by such Certificate, and the
Certificate so surrendered shall forthwith be cancelled.  No interest will be
paid or accrued on the cash payable upon the surrender of the Certificates.  If
payment of the Merger Consideration is to be made to a Person other than the
Person in whose name the surrendered Certificate is registered, it shall be a
condition of payment that the Certificate so surrendered shall be properly
endorsed or shall be otherwise in proper form for transfer and that the Person
requesting such payment shall have paid all transfer and other Taxes required by
reason of the issuance to a Person other than the registered holder of the
Certificate surrendered or shall have established to the satisfaction of the
Surviving Corporation that such Tax either has been paid or is not applicable.
Until surrendered as contemplated by this Section 2.8, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the Merger Consideration for each Share in cash as contemplated by this
Section 2.8.

              ---------------------------------------------------------      
the Effective Time, the stock transfer books of the Company shall be closed, and
thereafter there shall be no further registration of transfers of the Shares on
the records of the Company.  From and after the Effective Time, the holders of
Certificates evidencing ownership of the Shares outstanding immediately prior to
the Effective Time shall cease to have any rights with respect to such Shares,
except as otherwise provided for herein or by applicable law.  If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and exchanged as provided in this Article II.

          (d) Termination of Fund; No Liability.  At any time following the
              ---------------------------------                            
first anniversary of the Effective Time, the Surviving Corporation shall be
entitled to require the Exchange  Agent to deliver to it any funds (including
any interest received with respect thereto) which had been made available to the
Exchange Agent, and holders shall be entitled to look to the Surviving
Corporation (subject to abandoned property, escheat or other similar laws) only
as general creditors thereof with respect to the Merger Consideration payable
upon due surrender of their Certificates without any interest thereon.
Notwithstanding the foregoing, neither the Surviving Corporation nor the
Exchange Agent shall be liable to any holder of a Certificate for Merger
Consider ation delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

          (e) Lost, Stolen or Destroyed Certificates. In the event any
              --------------------------------------                  
Certificates for Shares shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the Person claiming such Certificate(s)
to be lost, stolen or destroyed and, if required by Alcoa, the posting by such
Person of a bond in such sum as Alcoa may reasonably direct as indemnity against
any claim that may be made against it or the Surviving Corporation with respect
to such Certificate(s), the Exchange Agent will issue the Merger Consideration
pursuant to Section 2.8(b) deliverable in respect of the Shares represented by
such lost, stolen or destroyed Certificates.

          (f) Withholding Taxes.  Alcoa and the Purchaser shall be entitled to
              -----------------                                               
deduct and withhold, or cause the Exchange Agent to deduct and withhold, from
the Offer Price or the Merger Consideration payable to a holder of Shares
pursuant to the Offer or the Merger any such amounts as are required under the
Internal Revenue Code of 1986, as amended (the "Code"), or any applicable
provision of state, local or foreign Tax law. To the extent that amounts are so
withheld by Alcoa or the Purchaser, such withheld amounts shall be treated for
all purposes of this Agreement as having 

                                       10

 
been paid to the holder of the Shares in respect of which such deduction and
withholding was made by Alcoa or the Purchaser.


          Section 2.9  Appraisal Rights. Notwithstanding anything in this
                       ----------------                                  
Agreement to the contrary, Shares (the "Dissenting Shares") that are issued and
outstanding immediately prior to the Effective Time and which are held by
stockholders who did not vote in favor of the Merger and who comply with all of
the relevant provisions of Section 262 of the DGCL (the "Dissenting
Stockholders") shall not be converted into or be exchangeable for the right to
receive the Merger Consideration, unless and until the holder or holders thereof
shall have failed to perfect or shall have effectively withdrawn or lost their
rights to appraisal under the DGCL.  If any Dissenting Stockholder shall have
failed to perfect or shall have effectively withdrawn or lost such right, such
holder's Shares shall thereupon be converted into and become exchangeable for
the right to receive, as of the Effective Time, the Merger Consideration for
each Share without any interest thereon.  The Company shall give Alcoa (i)
prompt notice of any written demands for appraisal of any Shares, attempted
withdrawals of such demands and any other instruments served pursuant to the
DGCL and received by the Company relating to stockholders' rights of appraisal,
and (ii) the opportunity to direct all negotiations and proceedings with respect
to demands for appraisal under the DGCL.  Neither the Company nor the Surviving
Corporation shall, except with the prior written consent of Alcoa, voluntarily
make any payment with respect to, or settle or offer to settle, any such demand
for payment.  If any Dissenting Stockholder shall fail to perfect or shall have
effectively withdrawn or lost the right to dissent, the Shares held by such
Dissenting Stockholder shall thereupon be treated as though such Shares had been
converted into the right to receive the Merger Consideration pursuant to Section
2.7(b).

                         --------------------------------------------------
Violation.
--------- 

          (a) The Company has the corporate power and authority to enter into
this Agreement and to carry out its obligations hereunder. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly and validly authorized by the Board of Directors of the
Company and, except for obtaining the Company Stockholder Approval and the
filing of the Certificate of Merger or the Certificate of Ownership and Merger,
as applicable, no other corporate proceedings on the part of the Company are
necessary to authorize the consummation of the transactions contemplated hereby.
The Board of Directors of the Company approved for purposes of Section 203 of
the DGCL the entering into by Alcoa, the Purchaser and the Company of this
Agreement and the consummation of the transactions contemplated hereby and has
taken all appropriate action so that Section 203 of the DGCL, with respect to
the Company, will not be applicable to Alcoa and the Purchaser by virtue of such
actions.  The Board of Directors of Howmet approved for purposes of Section 203
of the DGCL Alcoa and the Purchaser becoming "interested stockholders" pursuant
to Alcoa executing a letter agreement, dated March 13, 2000 with Howmet or their
entry into an agreement with the Company providing for a tender offer by the
Purchaser to acquire the outstanding Shares, to be followed by a merger in which
Alcoa would acquire the remaining Shares, and the consummation of such
transactions and the Board of Directors of Howmet has taken all appropriate
action so that Section 203 of the DGCL, with respect to Howmet, will not be
applicable to Alcoa and the Purchaser by virtue of such actions.  This Agreement
has been duly and validly executed and delivered by the Company and, assuming
this Agreement constitutes a valid and binding agreement of Alcoa and the
Purchaser, constitutes a valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms.

approvals set forth in Section 3.3(b)(i) of the Company Disclosure Schedule or

Act"), the Exchange Act, the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the "HSR Act"), state securities or blue sky laws, the rules

                         --------------------------------                  
previously furnished or otherwise made available (by electronic filing or
otherwise) to Alcoa true and complete copies of:

               (a) the Annual Reports on Form 10-K filed by the Company with the
SEC for the fiscal year ended June 30, 1998 and the fiscal period ended December
31, 1998, and the Annual Reports on Form 10-K filed by Howmet with the SEC for
each of the fiscal years ended December 31, 1997 and 1998;

               (b) the Quarterly Reports on Form 10-Q filed by each of the
Company and Howmet with the SEC for the quarters ended March 31, 1999, June 30,
1999 and September 30, 1999;

               (c) each definitive proxy statement filed by each of the Company
and Howmet with the SEC since December 31, 1997;

                                       16

 
               (d) each final prospectus filed by each of the Company and Howmet
with the SEC since December 31, 1997, except any final prospectus on Form S-8;
and

               (e) all Current Reports on Form 8-K filed by each of the Company
and Howmet with the SEC since January 1, 1998.

As of their respective dates, such reports, proxy statements and prospectuses
filed by the Company (collectively with, and giving effect to, any amendments,
supplements and exhibits thereto, the "Company SEC Reports") and filed by Howmet

respects with the applicable requirements of the Securities Act, the Exchange
Act and the rules and regulations promulgated thereunder in effect as of the
date of filing, and (ii) did not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they

recurring year-end adjustments), and in each case were prepared in accordance
with generally accepted accounting principles in the United States ("GAAP")
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto).  Since January 1, 1999, each of the Company and Howmet
has timely filed all reports, registration statements and other filings required
to be filed by it with the SEC under the rules and regulations of the SEC.The
Company 

                                       17

 
represents and warrants to Alcoa that, as of the respective dates
thereof, all reports of the type referred to in this Section 3.4 which the
Company files with the SEC on or after the date hereof, will not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The audited
consolidated financial statements and the unaudited consolidated interim
financial statements included in such reports (including any related notes and
schedules) will fairly present in all material respects the consolidated
financial position of the Company and its consolidated Subsidiaries as of the
dates thereof and the results of operations and cash flows or other information
included therein for the periods or as of the date then ended (subject, in the
case of the interim financial statements, to normal, recurring year-end
adjustments), and will be prepared in each case in accordance with GAAP
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto).

the aggregate for more than $60 million in revenues in the Company's 1999 fiscal
year. At the request of Alcoa, the Company shall agree to divest, hold separate
or otherwise take or commit to take any action that limits its freedom of action
with respect to, or its ability to retain, any of the businesses, product lines
or assets of the Company or any of its Subsidiaries, provided that any such
action shall be conditioned upon the consummation of the purchase of Shares in
the Offer. Prior to making any application to or filing with a Governmental
Entity or other entity in connection with this Agreement (other than filing
under the HSR Act), each party shall provide the other party with drafts thereof
and afford the other party a reasonable opportunity to comment on such drafts.

          (b) The Company, Alcoa and the Purchaser shall keep the other
reasonably apprised of the status of matters relating to completion of the
transactions contemplated hereby, including promptly furnishing the other with
copies of notices or other communications received by Alcoa, the Purchaser or
the Company, as the case may be, or any of their respective Subsidiaries, from
any third party and/or any Governmental Entity with respect to the transactions
contemplated by this Agreement.

          Section 5.5    Employee Stock Options and Other Employee Benefits.
                         -------------------------------------------------- 

          (a) The Company shall use its reasonable best efforts to cause each
outstanding option to purchase shares of Company Common Stock (including any
related alternative rights) granted under any stock option or compensation plan
or arrangement of the Company or its Subsidiaries (collectively, the "Company
Option Plans") (including those granted to current or former employees and
directors of the Company or any of its Subsidiaries) (the "Employee Stock
Options") to become exercisable, and each share of restricted Company Common
Stock granted under the Company Option Plans, to vest in full and become fully
transferable and free of restrictions, either prior to the purchase of the
Shares pursuant to the Offer or immediately prior to the Effective Time, as
permitted pursuant to the terms and conditions of the applicable Company Option
Plan.  The Company shall offer to each holder of an Employee Stock Option that
is outstanding immediately prior to the first purchase of Shares pursuant to the
Offer (the "Purchase Date") (whether or not then presently exercisable or
vested) to cancel such Employee Stock Option in exchange for an amount in cash
equal to the product obtained by multiplying (x) the difference between the
Offer Price and the per share exercise price of such Employee Stock Option, and
(y) the number of shares of Company Common Stock covered by such Employee Stock
Option.  All payments in respect of such Employee Stock Options shall be made as
promptly as practicable after the Purchase Date, subject to the collection of
all applicable withholding Taxes required by law to be collected by the Company.
Each Employee Stock Option, the holder of which does not accept such offer, that
remains outstanding immediately before the Effective Time shall be assumed by
Alcoa and converted, effective as of the Effective Time, into an option with
respect to that number (the "New Share Number") of shares of common stock, par
value $1.00 per share, of Alcoa ("Alcoa Common Stock") that equals the number of
shares of Company Common Stock subject to such Employee Stock Option immediately
before the Effective Time, times an amount equal to the Merger Consideration
divided by the Alcoa Share Value (as defined below), rounded to the nearest
whole number, with a per-share exercise price equal to the aggregate exercise
price of such option immediately before the Effective Time, divided by the New
Share Number, rounded to the nearest whole cent; provided, that in the case of
any such option that was granted as an "incentive stock option" within the
meaning of Section 422 of the Code and did not cease to qualify as such as a
result of any acceleration of vesting provided for above or otherwise, the
number of shares shall be rounded down to the nearest whole number to determine
the New Share Number, and the new per-share exercise price shall be determined
by rounding up to the nearest whole cent.  The Alcoa Share Value means the
average of the daily high and low trading prices of the Alcoa Common Stock on
the New York Stock Exchange on each 

                                       37

 
trading day during the period of 30 days ending the second trading day prior to
the Effective Time. Upon the Effective Time or as soon as reasonably practicable
thereafter, Alcoa shall file with the SEC a Registration Statement or
Registration Statements on Form S-8 covering all shares of Alcoa Common Stock to
be issued pursuant to the options converted into options to purchase shares of
Alcoa Common Stock pursuant to the terms of this Section 5.5(a) and shall cause
such Registration Statement to remain effective so long as Alcoa continues to
have a registration statement on Form S-8 (or any successor form) outstanding
for other options to purchase Alcoa Common Stock. Prior to the Purchase Date,
the Company and Alcoa shall take all action as may be necessary to carry out the
terms of this Section 5.5.

          (b) For the period from the Purchase Date through and including
December 31, 2001, Alcoa shall, or shall cause the Company or the Surviving
Corporation to, maintain employee benefit plans, programs and arrangements which
are, in the aggregate, for the employees who were employees of the Company or
any Subsidiary of the Company immediately prior to the Purchase Date and
continue to be employees of Alcoa, the Surviving Corporation or any other
Subsidiary of Alcoa, no less favorable than those provided by the Company and
its Subsidiaries as of the Purchase Date.  Each person who is an employee or
former employee of the Company or its Subsidiaries immediately prior to the
Purchase  Date (a "Company Employee") shall, without duplication of benefits, be
given credit for all service with the Company or any of its Subsidiaries (and
service credited by the Company or any of its Subsidiar ies) prior to the
Purchase Date, using the same methodology utilized by the Company as of
immediately before the Purchase Date for crediting service and determining
levels of benefits, under (i) all employee benefit plans, programs and
arrangements maintained by or contributed to by Alcoa and its Subsidiaries
(including, without limitation, the Company and the Surviving Corporation) in
which such Company Employees become participants for purposes of eligibility to
participate, vesting and determination of level of benefits (excluding, however,
benefit accrual under any defined benefit plans), and (ii) severance plans for
purposes of calculating the amount of each Company Employee's severance
benefits.  Alcoa, the Company and the Surviving Company shall (x) waive all
limitations as to preexisting conditions exclusions and waiting periods with
respect to participation and coverage requirements applicable to the Company
Employees under any welfare benefit plans that such Company Employees may be
eligible to participate in after the Purchase Date, other than limitations or
waiting periods that are already in effect with respect to such employees and
that have not been satisfied as of the Purchase Date under any welfare benefit
plan maintained for the Company Employees immediately prior to the Purchase
Date, and (y) provide each Company Employee with credit for any co-payments and
deductibles paid prior to the 

                                       38

 
Purchase Date in satisfying any applicable deductible or out-of-pocket
requirements under any welfare plans that such Company Employees are eligible to
participate in after the Purchase Date.

          (c) Without limiting the generality of the foregoing, for the period
through and including December 31, 2001, Alcoa shall provide, and shall cause
its Subsidiaries (including, without limitation, the Company and the Surviving
Corporation) to provide Company Employees whose employment is terminated
following the Purchase Date with severance benefits on terms and conditions, and
in amounts, that are not less favorable than those provided under the Company
Severance Pay Plan.

          (d) Without limiting the generality of the foregoing, Alcoa shall
honor and provide, and/or shall cause it Subsidiaries (including, without
limitation, the Company and the Surviving Corporation) to honor provide, the
agreements and change-of-control payments and benefits set forth in Section
5.5(d) of the Company Disclosure Schedule.

          (e) The Company shall take the actions provided for in Item 4 of
Section 5.1 of the Company Disclosure Schedule with respect to its qualified
pension plans.

          Section 5.6    Takeover Statute.  If any "fair price," "moratorium,"
                         ----------------                                     
"control share acquisition" or other form of anti-takeover statute or regulation
shall become applicable to the transactions contemplated hereby, each of the
Company, Alcoa and the Purchaser and the members of their respective Boards of
Directors shall grant such approvals and take such actions as are reasonably
necessary so that the transactions contemplated hereby may be consummated as
promptly as practicable on the terms contemplated hereby and otherwise act to
eliminate or minimize the effects of such statute or regulation on the
transactions contemplated hereby.

          Section 5.7    No Solicitation by the Company.
                         ------------------------------ 

          (a) Neither the Company nor any of its Subsidiaries nor any of the
officers and directors of any of them shall, and the Company shall direct and
use its reasonable best efforts to cause its and its Subsidiaries' employees,
agents and representatives, including any investment banker, attorney or
accountant retained by it or any of its Subsidiaries (the Company, its
Subsidiaries and their respective officers, directors, employees, agents and
representatives being the "Company Representatives")

                                       39

 
not to, directly or indirectly through another Person, (i) initiate, solicit,
encourage or otherwise knowingly facilitate any inquiries (by way of furnishing
information or otherwise) or the making of any inquiry, proposal or offer from
any Person which constitutes an Acquisition Proposal (or would reasonably be
expected to lead to an Acquisition Proposal) or (ii) participate in any
discussions or negotiations regarding an Acquisition Proposal; provided,
however, that the Company's Board of Directors may, or may authorize the Company
Representatives to, in response to an Acquisition Proposal that the Board of
Directors of the Company concludes in good faith is an Incipient Superior
Proposal, (x) furnish information with respect to the Company and its
Subsidiaries to any Person making such Acquisition Proposal pursuant to a
customary confidentiality agreement and (y) participate in discussions or
negotiations regarding such Acquisition Proposal, provided that, prior to taking
any such action, the Company provides reasonable advance notice to Alcoa that it
is taking such action. For purposes of this Agreement "Acquisition Proposal"
means any direct or indirect inquiry, proposal or offer (or any improvement,
restatement, amendment, renewal or reiteration thereof) relating to the
acquisition or purchase of a business or shares of any class of equity
securities of the Company or any of its Subsidiaries, any tender offer or
exchange offer that, if consummated, would result in any Person beneficially
owning any class of equity securities of the Company or any of its Subsidiaries,
or any merger, reorganiza tion, share exchange, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction
(a "Business Combination Transaction") involving the Company or any of its
Subsidiaries, or any purchase or sale of a substantial portion of the
consolidated assets (including without limitation stock of Subsidiaries owned
directly or indirectly by the Company) of the Company or any of its Subsidiaries
(an "Asset Transaction"), other than the transactions contemplated by this
Agreement or as permitted by Section 5.1 of this Agreement. For purposes of this
Agreement, (A) "Incipient Superior Proposal" shall mean an unsolicited bona fide
written Acquisition Proposal that the Board of Directors of the Company
concludes in good faith (after consultation with the Company's financial
advisor) would, if consummated, provide greater aggregate value to the Company's
stockholders from a financial point of view than the transactions contemplated
by this Agreement; provided that for purposes of this definition the term
"Acquisition Proposal" shall have the meaning set forth above, except that (x)
references to "shares of any class of equity securities of the Company" shall be
deemed to be references to "100% of the outstanding Shares" and (y) an
"Acquisition Proposal" shall be deemed to refer only to a Business Combination
Transaction involving the Company or, with respect to an Asset Transaction, such
transaction must involve the assets of the Company and its Subsidiaries, taken
as a whole, and not any Subsidiary of the Company alone and (B) "Superior
Proposal" shall mean an Incipient Superior Proposal for which any required
financing is committed or 

                                       40

 
which, in the good faith judgment of the Board of Directors in the Company
(after consultation with its financial advisor), is capable of being financed by
the Person making the Acquisition Proposal.

               (b) Except as expressly permitted by this Section 5.7, neither 
the Company's Board of Directors nor any committee thereof shall (i) withdraw,
modify or change, or propose publicly to withdraw, modify or change, in a manner
adverse to Alcoa, the recommendation by such Board of Directors or such
committee of the Offer, the Merger or this Agreement unless the Board of
Directors of the Company shall have determined in good faith, after consultation
with its financial advisor, that the Offer, the Merger or this Agreement is no
longer in the best interests of the Company's stockhold ers and that such
withdrawal, modification or change is, therefore, required in order to satisfy
its fiduciary duties to the Company's stockholders under applicable law, (ii)
approve or recommend, or propose publicly to approve or recommend, any
Acquisition Proposal, or (iii) cause the Company to enter into any letter of
intent, agreement in principle, acquisition agreement or other similar agreement
(each, an "Acquisition Agreement") related to any Acquisition Proposal.
Notwithstanding the foregoing, the Company may, in response to a Superior
Proposal, (x) take any of the actions described in clauses (i) or (ii) above or
(y) subject to this paragraph (b), terminate this Agreement (and concurrently
with or after such termination, if it so chooses, cause the Company to enter
into any Acquisition Agreement with respect to any Acquisition Proposal) but
only after the third business day following Alcoa's receipt of written notice
advising Alcoa that the Company's Board of Directors is prepared to accept an
Acquisition Proposal, and attaching the most current version of any such
Acquisition Proposal or any draft of an Acquisition Agreement; provided, the
Company is not in breach of any of its obligations under this Section 5.7.

          (c) In addition to the obligations of the Company set forth in
paragraphs (a) and (b) of this Section 5.7, the Company shall promptly (but in
any event within one business day) notify Alcoa orally and in writing of any
Acquisition Proposal or any inquiry regarding the making of any Acquisition
Proposal, indicating, in connection with such notice, the name of such Person
making such Acquisition Proposal or inquiry and the substance of any such
Acquisition Proposal or inquiry.  The Company thereafter shall keep Alcoa
reasonably informed of the status and terms (including amendments or proposed
amendments) of any such Acquisition Proposals or inquiries and the status of any
discussions or negotiations relating thereto.

          (d) Nothing contained in this Section 5.7 shall prohibit the Company
or its Board of Directors from at any time taking and disclosing to its

                                       41

 
stockholders a position contemplated by Rule 14e-2 promulgated under the
Exchange Act or from making any disclosure to the Company's stockholders
required by applicable law.

          Section 5.8    Public Announcements.  Alcoa and the Company agree that
                         --------------------                                   
neither one of them will issue any press release or otherwise make any public
statement or respond to any press inquiry with respect to this Agreement or the
transactions contemplated hereby without the prior approval of the other party
(which approval will not be unreasonably withheld or delayed), except as may be
required by applicable law or the rules of any stock exchange on which such
party's securities are listed.

          Section 5.9    Indemnification; Insurance. (a)  From and after the
                         --------------------------                         
Purchase Date, Alcoa will indemnify and hold harmless each present and former
director and officer of the Company and its Subsidiaries (the "Indemnified
Parties"), against any costs or expenses (including attorneys' fees), judgments,
fines, losses, claims, damages or liabilities incurred in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, by reason of the fact that such individual is
or was a director, officer, employee or agent of the Company or any of its
Subsidiaries, or is or was serving at the request of the Company or any of its
Subsidiaries as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, arising out of or
pertaining to matters existing or occurring at or prior to the Effective Time,
whether asserted or claimed prior to, at or after the purchase of Shares in the
Offer, to the fullest extent permitted under applicable law, and Alcoa shall
also advance fees and expenses (including attorneys' fees) as incurred to the
fullest extent permitted under applicable law.

          (b) The Certificate of Incorporation of the Company shall, from and
after the Purchase Date, and the Certificate of Incorporation of the Surviving
Corporation shall, from and after the Effective Time, contain provisions no less
favorable with respect to indemnification than are set forth as of the date of
this Agreement in Article Ninth of the Certificate of Incorporation of the
Company, which provisions shall not be amended, repealed or otherwise modified
for a period of six years from the Purchase Date in any manner that would
adversely affect the rights thereunder of individuals who at the Purchase Date
were directors, officers or employees of the Company; provided that nothing
contained herein shall limit Alcoa's ability to merge the Company into Alcoa or
any of its Subsidiaries or otherwise eliminate the Company's corporate
existence.

                                       42

 
          (c) For six years from the Effective Time, Alcoa shall maintain in
effect the Company's and its Subsidiaries' current directors' and officers'
liability insurance policy (the "Policies") covering those persons who are
currently covered by the Policies; provided, however, that in no event shall
Alcoa be required to expend in any one year an amount in excess of the annual
premiums currently paid by the Company and its Subsidiaries for such insurance,
and, provided, further, that if the annual premiums of such insurance coverage
exceeds such amount, Alcoa shall be obligated to obtain policies with the
greatest coverage available for a cost not exceeding such amount; and provided,
further, that Alcoa may meet its obligations under this paragraph by covering
the above persons under Alcoa's insurance policy on the terms described above
that expressly provide coverage for any acts which are covered by the existing
policies of the Company and its Subsidiaries.

          (d) Nothing in this Agreement is intended to, shall be construed to,
or shall release, waive or impair any rights to directors' and officers'
insurance claims under any policy that is or has been in existence with respect
to the Company or any of its Subsidiaries or any of their respective officers,
directors or employees, it being understood and agreed that the indemnification
provided for in this Section 5.9 is  not prior to or in substitution for any
such claims under such policies.

          Section 5.10   Disclosure Schedule Supplements.   From time to time
                         -------------------------------                     
after the date of this Agreement and prior to the Effective Time, the Company
will promptly supplement or amend the Company Disclosure Schedule with respect
to any matter hereafter arising which, if existing or occurring at or prior to
the date of this Agreement, would have been required to be set forth or
described in the Company Disclosure Schedule or which is necessary to correct
any information in a schedule or in any representation and warranty of the
Company which has been rendered inaccurate thereby in any material respect;
provided, however, that the Company may not update Sections 5.1 and 5.5(d) of
the Company Disclosure Schedule.  For purposes of determining the accuracy of
the representations and warranties of the Company contained in this Agreement in
order to determine the fulfillment of the conditions set forth in clause (f) of
Annex A, the Company Disclosure Schedule shall be deemed to include only that
information contained therein on the date of this Agreement and shall be deemed
to exclude any information contained in any subsequent supplement or amendment
thereto.

          Section 5.11   Howmet Acquisition.  Nothing in this Agreement shall
                         ------------------                                  
prevent Alcoa or any affiliate of Alcoa from offering to acquire or agreeing
with Howmet to acquire all of the shares of Howmet Common Stock not owned by the
Company or any of its Subsidiaries (a "Howmet Transaction") in accordance with
the terms of the Corporate Agreement, dated as of December 2, 1997, by and among
the Company, Cordant Technologies Holding Company and Howmet, as amended;
provided, however, Alcoa agrees that it will not acquire any shares of Howmet
Common Stock prior to the Purchaser's purchase of Shares pursuant to the Offer.

Merger.  The respective obligations of each party to effect the Merger shall be
------

conditions:

          (a) The Company Stockholder Approval shall have been obtained, if
required by applicable law.

          (b) No statute, rule, regulation, executive order, decree, ruling or
permanent injunction shall have been enacted, entered, promulgated or enforced
by any  Governmental Entity which prohibits the consummation of the Merger
substantially on the terms contemplated hereby or has the effect of making the
acquisition of Shares by Alcoa or the Purchaser or any affiliate of either of
them illegal.

          (c) Alcoa or the Purchaser or any affiliate of either of them shall
have purchased Shares pursuant to the Offer, except that this condition shall
not be a condition to Alcoa's and the Purchaser's obligation to effect the
Merger if Alcoa, the Purchaser or such affiliate shall have failed to purchase
Shares pursuant to the Offer in breach of their obligations under this
Agreement.

               (d) The applicable waiting period under the HSR Act shall have
expired or been terminated.

          Section 7.1        Termination.  This Agreement may be terminated and
                             -----------                                       
the other transactions contemplated herein abandoned at any time prior to the
Effective Time, whether before or after obtaining the Company Stockholder
Approval:

          (a) by the mutual written consent of the Company (including, from and
after the Purchase Date, the Independent Director Approval contemplated by
Section 1.3(c)), Alcoa and the Purchaser;

          (b) by either Alcoa or the Company if (i) (1) the Offer shall have
expired without any Shares being purchased pursuant thereto, or (2) the Offer
has not been consummated on or before September 30, 2000 (the "Drop Dead Date");
provided, however, that the right to terminate this Agreement pursuant to this
Section 7.1(b)(i) shall not be available to any party whose failure to fulfill
any obligation under this Agreement or the Offer has been the cause of, or
resulted in, the failure of the Shares to have been purchased pursuant to the
Offer; (ii) a statute, rule, regulation or executive order shall have been
enacted, entered or promulgated prohibiting the consummation of the Offer or the
Merger substantially on the terms contemplated hereby; or (iii) an order,
decree, ruling or injunction shall have been entered perma nently restraining,
enjoining or otherwise prohibiting the consummation of the Offer or the Merger
substantially on the terms contemplated hereby and such order, decree, ruling or
injunction shall have become final and non-appealable; provided, that the party
seeking to terminate this Agreement pursuant to this Section 7.1(b)(iii) shall
have used its reasonable best efforts to remove such order, decree, ruling or
injunction and shall not be in violation of Section 5.4;

          (c) by Alcoa, if due to an occurrence or circumstance, other than as a
result of a breach by Alcoa or the Purchaser of its obligations hereunder or
under the Offer, resulting in a failure to satisfy any condition set forth in
Annex A hereto, the Purchaser shall have (i) failed to commence the Offer within
30 days following the date of this Agreement, or (ii) terminated the Offer
without having accepted any Shares for payment thereunder;

          (d) by the Company, upon approval of its Board of Directors, if the
Purchaser shall have terminated the Offer without having accepted any Shares for
payment thereunder, other than as a result of a breach by the Company of its
obligations 

                                       45

 
hereunder, that would result in a failure to satisfy any of the
conditions set forth in Annex A hereto;

          (e) by the Company, in accordance with Section 5.7(b); provided, that
such termination shall not be effective unless and until the Company shall have
paid to Alcoa the fee described in Section 7.3 hereof and shall have complied
with the provisions of Sections 5.7(b) and (c).

          Section 7.2    Effect of Termination.  In the event of termination of
                         ---------------------                                 
this Agreement pursuant to Section 7.1, written notice thereof shall forthwith
be given to the other party or parties specifying the provision hereof pursuant
to which such termination is made, and this Agreement shall terminate and be of
no further force and effect (except for the provisions of Sections 5.2, 7.3 and
8.2 in the case of termination of this Agreement at any time, and Section 5.5 in
the case of a termination following the purchase of Shares pursuant to the
Offer), and there shall be no other liability on the part of Alcoa, the
Purchaser or the Company or their respective officers or directors except
liability arising out of a willful breach of this Agreement.  In the event of
termination of this Agreement pursuant to Section 7.1 prior to the expiration of
the Offer, Alcoa and the Purchaser will promptly terminate the Offer upon such
termination of this Agreement without the purchase of Shares thereunder.

          Section 7.3    Termination Fee.  In the event that this Agreement
                         ---------------                                   
shall have been terminated pursuant to Section 7.1(c) as a result of the failure
of the condition of the Offer set forth in paragraph (e) of Annex A hereto or
Section 7.1(e), the Company shall immediately pay Alcoa a fee equal to $75
million (the "Termination Fee"), payable by wire transfer of immediately
available funds, the receipt of which by Alcoa in the case of termination
pursuant to Section 7.1(e), shall be a condition to the effectiveness of such
termination.  The Company acknowledges that the agreements contained in this
Section 7.3 are an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, Alcoa and the Purchaser would not
enter into this Agreement; accordingly, if the Company fails to pay the amount
due pursuant to this Section 7.3, and, in order to obtain such payment, Alcoa
commences a suit which results in a judgment against the Company for the fee set
forth in this Section 7.3, the Company shall pay to Alcoa its costs and expenses
(including attorneys' fees and expenses) in connection with such suit, together
with interest on the amount of the fee at the prime rate of Citibank N.A. in
effect on the date such payment was required to be made.

Adverse Effect on the Company to the extent that it relates to or arises out of

Alcoa's, the Purchaser's and the Company's obligations under Section 5.4 of the
Agreement;

or interpretation enacted, enforced, promulgated, amended or, issued by any

Alcoa, the Company or any Subsidiary or affiliate of Alcoa or the Company or
(ii) any transaction contemplated by this Agreement, other than the HSR Act, the
EU Council Regulation 4064/89, as amended, and the Canadian Competition Act,
which is reasonably likely to result, directly or indirectly, in any of the
consequences referred to in clauses (i) through (v) of paragraph (a) above,
except where such events are consistent with or result from Alcoa's, the
Purchaser's and the Company's obligations under Section 5.4 of the Agreement;

          (c) there shall have occurred any changes, conditions, events or
developments that would have, or be reasonably likely to have, individually or
in the aggregate, a Material Adverse Effect on the Company;

commencement of the Offer, a material acceleration or worsening thereof;

          (e) (i) it shall have been publicly disclosed or the Purchaser shall
have otherwise learned that any Person, other than Alcoa or any of its
affiliates, shall have acquired or entered into a definitive agreement or
agreement in principle to acquire beneficial ownership (determined for the
purposes of this paragraph as set forth in Rule 13d-3 promulgated under the
Exchange Act) of the then outstanding Shares, or shall have been granted any
option, right or warrant, conditional or otherwise, to acquire 

                                      ii

 
beneficial ownership of 50% or more of the then outstanding Shares, or (ii) the
Board of Directors of the Company or any committee thereof shall have (A)
withdrawn, modified or changed, in a manner adverse to Alcoa or the Purchaser,
the recommenda tion by such Board of Directors or such committee of the Offer,
the Merger or this Agreement, (B) approved or recommended, or proposed publicly
to approve or recommend, an Acquisition Proposal, (C) caused the Company to
enter into any Acquisition Agreement relating to any Acquisition Proposal, or
(D) resolved to do any of the foregoing;

          (f) the representations or warranties of the Company set forth in the
Agreement that are qualified by materiality or Material Adverse Effect shall not
be true and correct, or the representations and warranties of the Company set
forth in the Agreement that are not so qualified shall not be true and correct
in all material respects, in each case, as if such representations or warranties
were made as of such time on or after the date of the Agreement (except to the
extent such representations and warranties speak as of a specific date or as of
the date hereof, in which case such representations and warranties shall not be
so true and correct or true and correct in all material respects, as the case
may be, as of such specific date or as of the date hereof, respectively);

          (g) the Company shall have failed to perform in any material respect
any material obligation or to comply in any material respect with any material
agreement or covenant of the Company to be performed or complied with by it
under the Agreement;

          (h) the Agreement shall have been terminated in accordance with
its terms; or

          (i) the Purchaser and the Company shall have agreed that the Purchaser
shall terminate the Offer or postpone the acceptance for payment of or payment
for Shares thereunder;

which, in the reasonable good faith judgment of the Purchaser in any such case,
and regardless of the circumstances (including any action or inaction by Alcoa
or any of its affiliates) giving rise to any such condition, makes it
inadvisable to proceed with such acceptance for payment or payment.

          The foregoing conditions are for the benefit of the Purchaser and
Alcoa and may be asserted by the Purchaser or Alcoa regardless of the
circumstances giving rise to any such condition or may be waived by the
Purchaser or Alcoa in whole or in 

                                      iii

 
part at any time and from time to time in their reasonable discretion. The
failure by Alcoa or the Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right; the waiver of any such
right with respect to particular facts and other circumstances shall not be
deemed a waiver with respect to any other facts and circumstances; and each such
right shall be deemed an ongoing right that may be asserted at any time and from
time to time.
